QuickBox2D Skinning Examples

Geoff Gaudreault

I don’t know if you’re doing it this way, but for my own game engine I can create a special “bounds” Sprite that is a rectangle representing the collision width and height. The engine will set that object to visibility=false, but use its dimensions for the physics engine.

cool,

thx for the bug correction.

Hey, do you know how can I skin rigid bodies in flex develop or flashdevelop?

CD

Your classes have my life SO much easier and really appreciate your work!
But - Is there any way to change the width/height/scale of an object already defined? Thanks!

Zevan, I have the same problem as Nicolas, do you have any idea why scaling skin doesn’t work properly?

And yes I tried to run your .fla file

Hi there, firstly I absolutely love what your doing with this! But i find my skins don’t autoscale to the size of my rigid bodies. Even if I download FLA’s from this page and run them, all the skins remain their original sizes regardless of “scaleSkin:true”. Any idea what could be causing this? Thanks

I’m using box2D version 2.0.2 and Quickbox2D version 1.1. If I download and publish this .FLA http://www.actionsnippet.com/swfs/skinning/lib_skinning.fla it runs fine with no errors but the skins are all the same size. Even though the 3 same-skinned balls are 3 different physical sizes. Thanks for looking at this for me, it looks like there are a few people experiencing the same issue.

Ok i feel like a complete idiot. It turns out i was in fact using the latest version of Box2D with version 1.0 of Quickbox. Even though i had downloaded 1.1 I was still linking to the old version in my build path. Changing to version 1.1 of Quickbox solved the issue!

Thanks for your help anyway and keep up the good work mate!

“another way would be just using bitmaps and Loaders…. lot of different options…”

I’m trying to cobble together an example with using loaders and I’m so far unsuccessful. It looks like CircleObject is just checking for a Display Object. In this example I’m waiting until a bitmap is loaded in, wrapping it in a sprite and trying to set it as the skin.

package
{
	import com.actionsnippet.qbox.*;

	import flash.display.Loader;
	import flash.display.MovieClip;
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.net.URLRequest;

	public class SimpleSkin extends MovieClip
	{

		private var _ldr:Loader;

		public function SimpleSkin()
		{
			var req:URLRequest = new URLRequest("images/thumb.png");
			_ldr = new Loader();
			_ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, imgLoaded);
			_ldr.load(req);
		}

		private function imgLoaded(e:Event):void {
			var s:Sprite = new Sprite();
			s.addChild(_ldr.content);

			stage.frameRate = 60;

			var sim:QuickBox2D = new QuickBox2D(this, {debug:false});
			sim.createStageWalls();

			sim.addCircle({skin:s});//sprite just sits there... 

			sim.start();
			sim.mouseDrag();
		}

	}
}

It seems to be getting stuck. Also, if there were a way to set a skin after an object was constructed that would be awesome too, but I could see reasons for not wanting that.

Library skinning works great, but when I create a skin class, it attaches well, but doesn’t scale the skin… any hints?

Hello. This library does make my life easier!

however, is there any way to use an INSTANCE instead of Class for skin? So that you can do stuff like this :
q.addCircle({ skin:new CustomSkin(”ball.png”) });
or maybe
QObj.setSkin(new CustomSkin(”ball.png”));

I’m facing a problem with skining.
It works great with box and circles, but not with polys.

Is there a way to skin AND display the wireframe? I’d like to tweak my polygon/skin combo.
